Question:

Gopi buys a fish from a shop for his aquarium. The shopkeeper takes out one fish at random from a tank containing 5 male fish and 8 female fish (see the given figure). What is the probability that the fish taken out is a male fish?

Solution:

Total number of fishes in a tank

= Number of male fishes + Number of female fishes

= 5 + 8 = 13

Probability of getting a male fish $=\frac{\text { Number of favourable outcomes }}{\text { Number of total possible outcomes }}$

$=\frac{5}{13}$
